He stirred again, and suddenly jerked upright with a protest already forming on his lips. The ugly surroundings registered on his eyes, and he stared suspiciously at the other cots. But there was no sign that anyone had been trying to rob him of his bindle or the precious bag of cheap tobacco. He started to relax back onto the couch when a sound caught his attention, even over the snoring of the others. It was a low wail, the sound of a man who can no longer control himself. Feldman swung to the cot on his left as the moan hacked off. The man there was well fed and clean-shaven, but his face was gray with sickness. He was writhing and clutching his stomach, arching his back against the misery inside him. "Space-stomach?" Feldman diagnosed. He had no need of the weak answering nod. He'd treated such cases several times in the past. The disease was usually caused by the absence of gravity out in space, but it could be brought on later from abuse of the weakened internal organs, such as the intake of too much bad liquor. The man must have been frequenting the wrong space-front bars. Now he was obviously dying. Violent peristaltic contractions seemed to be tearing the intestines out of him, and the paroxysms were coming faster. His eyes darted to Feldman's tobacco sack and there was animal appeal in them. Feldman hesitated, then reluctantly rolled a smoke. He held the cigarette while the spaceman took a long, gasping drag on it. He smoked the remainder himself, letting the harsh tobacco burn against his lungs and sicken his empty stomach. Then he shrugged and threaded his way through the narrow aisles toward the attendant. "Better get a doctor," he said bitterly, when the young punk looked up at him. "You've got a man dying of space-stomach on 214." The sneer on the kid's face deepened. "Yeah? We don't pay for doctors every time some wino wants to throw up. Forget it and get back where you belong, bo." "You'll have a corpse on your hands in an hour," Feldman insisted. "I know space-stomach, damn it." The kid turned back to his lottery sheet. "Go treat yourself if you wanta play doctor. Go on, scram--before I toss you out in the snow!" One of Feldman's white-knuckled hands reached for the attendant. Then he caught himself. He started to turn back, hesitated, and finally faced the kid again. "I'm not fooling. And I _was_ a doctor," he stated. "My name is Daniel Feldman." The attendant nodded absently, until the words finally penetrated. He looked up, studied Feldman with surprised curiosity and growing contempt, and reached for the phone. "Gimme Medical Directory," he muttered. Feldman felt the kid's eyes on his back as he stumbled through the aisles to his cot again. He slumped down, rolling another cigarette in hands that shook. The sick man was approaching delirium now, and the moans were mixed with weak whining sounds of fear. Other men had wakened and were watching, but nobody made a move to help.
